摘要： An optical wavelength multiplexing system includes transmission-side and reception-side optical wavelength multiplexers, and terminal devices, which are connected to each other by optical fiber cables. Optical wavelength converters in the transmission-side optical wavelength multiplexers are connected to ports respectively. The optical wavelength converter converts an input optical signal into an arbitrary preset wavelength to generate a converted optical signal. The port has a predetermined wavelength preset therein. Each optical power level of input converted optical signals is compared with each optical power level of optical signals of respective wavelengths set in the ports. When a difference is detected in the comparison result, it is determined that an optical wavelength converter is incorrectly connected to the port.

摘要： Even during a protection period in which a state transition is not caused from an ALC state to an ALD state, when an output light level that is inputted is below a threshold for ALC transition read from a memory, a processor causes a transition by switching an internal state from an ALC state to an ALD state. Then, an ALD operation is started, outputting a control voltage to a VAT control unit so as to achieve a predetermined fixed attenuation amount.

摘要： A transmission apparatus designed to be capable of monitoring faults which occur between the input stage of an optical multiplexer and the input stage of an optical amplifier, appropriately switching between automatic gain control and automatic level control, and outputting signal lights with appropriate optical power, without using a spectrum analyzer. The optical multiplexer combines the wavelengths of a plurality of signal lights. The optical amplifier is connected at the latter stage of the optical multiplexer, and operates in the automatic gain control mode or in the automatic level control mode, the automatic gain control mode maintaining a constant gain for wavelength-multiplexed signal light, the automatic level control mode maintaining constant output power for the wavelength-multiplexed signal light. A mode selector selects the automatic gain control mode or the automatic level control mode for the optical amplifier based on the total optical power of the plurality of signal lights to be input to the optical multiplexer and the optical power of the wavelength-multiplexed signal light to be input to the optical amplifier.
